    摘要： A motion vector prediction method in an error resilient mode. In the motion vector prediction method capable of decoding backwards, motion vectors of macro blocks are calculated, and motion vectors of macro blocks each having one motion vector are predicted while moving to another macro block from left to right, and motion vectors of macro blocks each having four motion vectors are continuously predicted in a predetermined sequence to have correlation in prediction of the four motion vectors. Thus, in the motion vector prediction method based on the image signal compression method of the MPEG-4 or H.263 standard, the motion vector prediction is performed with continuity and correlation among the motion vectors, so that two-way decoding is possible during transmission of blocks with a predetermined packet, resulting in better error resilient characteristics.

    摘要： A method and computer program product for performing error control of video bitstream data encoded according to a data partition technique used in communication through a wireless channel. The method includes the steps of (a) partitioning video bitstream data into units of information items having certain characteristics and encoding the video bitstream data, (b) calculating a checksum for controlling errors in each partitioned unit of the encoded video bitstream data, (c) constituting a packet, in which each checksum calculated in a the step (b) is added to the encoded video bitstream data and transmitting the packet through a wireless communication channel, and (d) receiving the packet transmitted in the step (c) and checking whether there is an error in each partitioned unit of the encoded video bitstream data through the checksum of each partitioned unit of the encoded video bitstream data. According to the above method, it is possible to effectively detect the errors of the respective partitioned video bitstream data items and to use partial data without abandoning the entire video bitstream packet when errors occur in a specific portion of the video bitstream data by calculating the CRCs of the respective partition regions of the video bitstream data encoded according to a data partition technique.

    摘要： A wide band radio transmission method, apparatus and computer readable medium for transmitting bit streams of a video-related application through a radio channel are provided. The wide band radio transmission method comprises the steps of: (a) obtaining identification information on a video-related application which is executed in a user layer, from the user layer; (b) obtaining information on at least one of channel characteristics and a decoding state from a physical layer; and (c) deciding on a quality of service (QoS) level with reference to the identification information and the information on at least one of the channel characteristics and the decoding state from the physical layer. The wide band radio transmission method can efficiently support video-related applications such as applications of the H.324M standard, the H.323 standard, the H.320 standard, and the MPEG-4 standard. Also, negotiations on video services having different quality of service (QoS) levels can be performed, and then, optimum video services considering channel characteristics can be provided.
